Abstract (en)

The present invention pertains to a process for the separation of methanol and water from non-condensables wherein a feed stream comprising methanol, water and non-condensables is subjected to a membrane separation step at a temperature of at least 150°C and a pressure of at least 1 bar (100 kPa) thereby separating the mixture into a permeate being enriched in methanol and water as compared to the feed stream and a retentate being leaner in methanol and water as compared to the feed stream, characterized in that the membrane separation step is carried out using a membrane comprising a separating layer of sulfonated poly ether.
